Season 2
Overview
An increase in villain activity has the Hero Organization worried that the "Earthdoom prophecy" will soon come to pass. In an effort to alleviate the overworked heroes, they turn to villains themselves for help. The decision looks ill-advised as at least one villain is more interested in helping the prophecy along than preventing it.
